Specification of Letters Patent. Patented N 6 1917 Application filed July 25, 1917. Serial No. 182,756.

Toall whom it may concern:

Be it known that I, Mosns C.v NIXON, of the city of Chicago, in. the county of Cook and State of Illinois, have invented certain new and useful Improvements in Windmills, of which the followin is a Specification.

The objects of the inventionare to provide for automatic lubrication of certainwith parts broken away; Fig. 3 is a section of obscure parts of Fig. 1, on a reduced scale, and at right angles to the same; Fig. 4 is an enlarged sectional view of a part of the cams, cut through the spill-way, showing bucket inconnection with one of the cams for elevating the oil and part of the runway that conveys the oil to journal bearings; Fig. 5 is an enlarged sectional view of a art of the gear-wheel, cut through the spill-way,

' showing bucket in connection therewith for elevating the. oil from the reservoir and a part of the run-way that conveys oil to j ournal bearings; Fig. 6 is the central part of the pull-out lever and a section of the mainframe, showing arrangement whereby open space between the lever and incasement is obviated when the lever is rocked; Fig. 7 is a part of the main-frame and ull-out lever,

showing a modifiediorm of t e latter, and.

Fig. 8 is a sectional view showing the chamber or reservoir in the hubs of lever 15, pitman 14 and the pump-rod head, witha loop of felt therein.

In the drawings, similar numerals of reference indicate corresponding parts in the different views, and referring to the same, 1

is the incasement, which in this case is also a the main-frame, and 2 is a covering for the same. Journaled in the main-frame is the wheel or driving shaft 3, to which is rigidly secured gear-pinion 4. This pinion meshes with and drives the gear-wheel 5, secured to shaft 6, journaled in the main-frame. Secured to shaft 6 is a double cam or two cams 7 and 8 side by side. Secured to the main- .frame is a shaft 9, the front-bearing of which is removed to better show the inter1or. Pivotally mounted on shaft 9 is a rocking frame 10, which carries two rollers, of which roller 11 contacts with cam 7 and roller 12 with cam 8. As they revolve, one cam forces its mating roller outwardly carrylng with it the rocking frame; then as the full movement in that direction is reached the other cam drives its mating roller and the frame in the opposite direction, thus creating a rocking movement of the, frame.

Pivotally secured to this rocking frame at 13 is a pitman 14, which is pivotally connected with lever115, as by pivot-pin 16. Said lever is ivoted on shaft 17, and to its free end is plvotally secured the pump-rod 18, as by pivot-pin 19. As the pivot-pin 16 is tapped into lever 15 the length of stroke of t e pump-rodmay 'be increased or decreased by shifting said piv0t-pin to threaded holes 20 or 21 as the case may require.

The cams 7 and 8 are so shaped and proportioned that the movement of the rock ing frame will be comparatively slowwith increased power while lifting the load and with a comparatively quick return. As the weight of the pump-rod assists the power on the down stroke and acts against it on the upward stroke, .it is evident that less power is required to force the plunger downward than to raise it; hence a more rapid speed is possible on the downstroke than on the upstroke. The demand on the power is thus equalized by constructing the cams as already described, enabling it to perform the work with less power or wind.

For the purpose of furnishing automatic lubrication for certain arts, the incasement or main-frame 1 is ma e to form a reservoir 22, for holding a supply of oil, in which a piece of tubing 23 is firmly secured in line of the tubular mast 24, so as to afford free working space for the pump-rod, and extends upwardly to a point above surface 25 of the oil. This tubing 23 may be either a separate piece, an extension of the tubular mast, or may be in a tubular form cast integral with the incasement, but in either case it is essential that it be so constructed as to form a dependable container for a supply of oil. As it is necessary to retain and return the surplus oil from the journal bearings to the reservoir, said bearings are inclosed in extensions 1 and 1" of the 2 erraces incasement, and the bolts for securing the bearings are anchored by placing their heads into grooves 27. It being necessary to extend the wheel shaft 3 through the incasement a closely fitting washer 28 on said shaft is provided to turn back the surplus oil, and to give it free access to the reservoir, channels 29 beneath the bearings and open spaces 30 between them and the incasement are provided.

Opposite each other and in connection wlth cam 7 and for lubricat ng the journal bearings, in WhlCll are provided buckets 31, 31 with openings or spill-ways 32, 32, so that as the cam and gear Wheel revolve these buckets will elevate oil from the reservoir and in passing spill it into run-ways 33, 33 and 34, 34. Run-ways 33, 33' convey the Oll to the bearings of shaft 3, through oil holes 35, 35; and the run-ways 34, 34 convey it to cups 36, 36 formed on the caps of the bearings, and to the bearings of shaft 6 through oil holes 37, 37. To automatically lubricate certain pivotal connections, the hubs 14', 15' and 18 of pitman 14, lever 15 and the head of the pump-rod 18, respectively, are chambered thereby forming reservoirs for a supply of lubricating oil, which may be carried combination with the covering 2, which is secured thereto, be storm-proof and that the pull-out mechanism be operated through the mast, a mechanism has been devised consisting of a bell-crank lever mounted on shaft 17 and having an operating arm 39 extending to a point over the mast, with a rod or wire 40 attached to its end, said wire leading down through the tubing 23 and mast 24, so as to be operative from below. This bell-crank lever has another 'arm4l extending downward through slotted opening 42 in the incasement, and its lower end is connected with a lug 43, by means of rod 44. Saidv lug is a rigid part of vane-hinge 45 which is pivotally connected to brackets, of which the upper bracket 46 extends from extension 1" of the incasement 1, and the lower bracket 47 extends from the lower part of said incasement (see Fig. 3) and ismuch longer, which allows ample room be tween the; incasement and the vane-hinge pivot to permit the lug 43 to pass between ear-wheel 5 are similar devices them. P The vane stem 48 is rigidly secured to the vane-hinge, is brokenofi in the draw; ings, andthe vane, which may be of the usual form, is not shown. Around the vanehinge pivot-pin-49 is placed torsion spring 50, which has a hook 51 at its upper end adapted to catch upon rib 52 of the vanehinge. The lower end of this sprin is turned'downwar'd and adapted to enter 53 in tension piece 54. This tension piece is ole placed upon the vane-hinge pin'and is provided with a rim 55, upon which the spring rests and its hub extends upwardly into the spring. At the upper end of this spring a rimmed collar 56 is provided, which extends downward into the spring, the rim 57 being intended to prevent the collar from working too far down. The object of this collar and the upwardly extending hub of the tension piece is to keep the spring centrally located as to the hinge-pin.

bracket 58, to which is attached a rod 59. Said rod passes through a hole in the arm of the tension piece and by the use of nut 60 the tension on the torsion spring may be adjusted to meet requirements. In operation of the pull-out mechanism, the rod 40 is drawn downward, depressing arm 39, forcingarm 41 outwardly, carrying with it rod 44 and connecting parts, thereby causing .the vane topivot and permitting the mill to become-inoperative, and when released the torsion spring carries it back into normal position.

In Fig. 7 of the drawings, a modified form of the pull-out lever is shown, in which arm '39 is rigidly secured to shaft 17 said shaft extending through the wall of the incase ment, and to its outer end is rigidly secured arm 41, thus producing a modified form of the pull-out mechanism with the storm-proof feature. e v i To permit arm 41 of the pull-out lever to operate beneath the incasement the latter is out under as indicated in dotted outline 61 in Fig. 1, and shown in Figs. 2 and 3; and with a View of making the incasement more storm-proof, its Wall is brought close to the hub 62 of the pull-out'lever. -Said,

' hub is provided with a rim 63, which continually fills opening 42 at one end, and the web 64 that connects the two arms of the pull-out lever performs the same function at the other end, thereby preventing an open From 'the lower part of the incasement extends a space occurring when the lever is rocked.

Also to make the incasement more stormproof, the covering 2, which is preferably made of galvanized steel, is formed with an ofi'set 2 so as to rest upon the incasement and extends downwardly over the same, and is secured thereto.
